This Week In Pictures - 22/04/13

THIS week has been a busy one for the royal family. On Sunday, the Duchess of Cambridge honoured a group of scouts gathered at Windsor Castle - in recognition of particularly high achievements - then on Wednesday made a speech at the National Portrait Gallery to support charity The Art Room. Prince Harry quite literally made his mark in Nottingham, as he signed his name on a graffiti wall at a local youth club, before joining the Duchess and Duke of Cambridge today for a trip to the Warner Bros. Studio in Hertfordshire.

Elsewhere in the fashion world, Burberry hosted its first ever public gig with the Kaiser Chiefs, while Gwyneth Paltrow attracted headlines by wearing a very daring dress to the premiere of her new film, Iron Man 3. Gisele Bundchen showed her support for fellow supermodel Christy Turlington, as she showcased the US beauty's new collection of baby carriers.

Meanwhile, the annual GLAAD (Gay and Lesbian Alliance Against Defamation) Media Awards took place in Los Angeles, while California also played host to the second weekend of the Coachella Festival. Back in the UK, thousands of fundraisers took to the streets of the capital last weekend for the 2013 London Marathon - with an equally impressive turnout of supporters cheering them on in the sunshine. Click through the gallery to see all this week's unmissable pictures so far.
